[0001] This application claims priority to Chinese patent application No. CN 202311099185.1 filed on August 30, 2023, the contents of which are incorporated by reference into this application. Technical Field

[0002] The present invention relates to the field of transport devices, and in particular to a vehicle. Background Art

[0003] Currently, there are vehicles on the market that are driven by pushing or pulling, such as carts and trailers. The vehicles are usually provided with a carrying frame, and a carrying space is formed in the carrying frame. The carried person can sit or lie in the carrying space.

[0004] To facilitate daily storage and carrying, the carrying frame is usually designed as a foldable structure. In the prior art, these carrying frames are usually a closed structure in the circumferential direction, and the carried person needs the assistance of other people or objects to enter the carrying space, which causes inconvenience in daily use and also brings a burden to the caregiver. Summary of the Invention

[0005] An object of the present invention is to provide a carrier to solve one or more problems of the prior art.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] A carrier having a folded state and an unfolded state, comprising:

[0008] a first support structure;

[0009] a second supporting structure, rotatably connected to the first supporting structure, and the second supporting structure is foldable;

[0010] a connecting structure, rotatably connected to the second supporting structure and the first supporting structure respectively;

[0011] When the carrier is in the unfolded state, the first supporting structure extends along a first direction, the second supporting structure extends along a second direction different from the first direction, and an opening is formed between the connecting structure and the first supporting structure; when the carrier is in the folded state, the second supporting structure is folded, and the first supporting structure and the connecting structure are folded along the first direction.

[0012] In some embodiments, the first support structure includes at least two first support members respectively connected to the second support structure for rotation, and an associated structure respectively connected to the at least two first support members so that the two adjacent first support members can rotate relative to each other. The connection structure includes two connecting members, and the second support structure includes two second support members. Each of the connecting members and each of the second support members are respectively arranged on both sides of the associated structure, and the connecting members and the second support members on each side form a seating area with the first support member respectively to form two seating areas arranged opposite to each other.

[0013] Furthermore, when the vehicle is in an expanded state, the connecting structure, the first supporting structure, and the second supporting structure define a first surface of the vehicle, the opening is located on the first surface, and the opening is located between the two seat areas; when the vehicle is in a folded state, the two adjacent first supporting members rotate and fold relative to each other, and each of the connecting members and each of the second supporting members fold relatively toward the direction close to the associated structure.

[0014] Furthermore, each of the connecting members includes a first connecting portion and a second connecting portion that are rotatably connected to each other, the first connecting portion is also rotatably connected to the second supporting structure, and the second connecting portion is also rotatably connected to the first supporting structure.

[0015] In some embodiments, the vehicle also includes a third support structure, and the third support structure and the connecting structure are respectively arranged on the upper and lower sides of the first support structure, and the third support structure has a first extension member and a second extension member, and the first extension member and the second extension member respectively extend from the first support structure in a direction away from the first support structure, and are connected to each other at the extension ends to form a stepping area on the lower side of the first support structure.

[0016] Furthermore, the first extension member and the second extension member are respectively rotatably connected to the first support structure, and the extension ends of the first extension member and the second extension member are rotatably connected to each other around a first pivot center line X1, and the first pivot center line X1 is perpendicular to the first direction.

[0017] Furthermore, a line connecting the projection points of the first pivot center line X1 and the axis of the associated structure in the same vertical plane is perpendicular to the first direction.

[0018] Furthermore, the connecting structure and the first extension member are rotatably connected to the first support structure together around the second pivot center line X2, and the connecting structure and the second extension member are rotatably connected to the first support structure together around the third pivot center line X3.

[0019] In some embodiments, the first extension member and the second extension member are respectively integrally provided with at least a portion of the connecting structure.

[0020] In some embodiments, the first extension member and the second extension member are independent of the connecting structure, and the carrier also includes a first locking structure, which is coupled to the connecting structure and the first extension member or the second extension member, respectively, so that the connecting structure and the first extension member or the second extension member can be locked with each other.

[0021] In some embodiments, in the expanded state, the position of the axis of the associated structure is lower than the positions of the second pivot center line X2 and the third pivot center line X3.

[0022] In some embodiments, a first space is formed between the two seating areas, and the first space is communicated with the opening and the stepping area respectively.

[0023] In some embodiments, each of the first support members has a first end and a second end, the first end being connected to the associated structure, and the second end being connected to the second support structure;

[0024] When the carrier enters the folded state from the unfolded state, the first ends of two adjacent first support members rotate relative to each other, and drive the second ends to move in a coordinated manner so that the second ends of the two adjacent first support members approach each other.

[0025] In some embodiments, a pivot structure is provided between the first support structure and the second support structure, and the pivot structure is rotatably connected to at least one of the first support structure and the second support structure. When the carrier moves from an unfolded state to a folded state, the second end of the first support member moves away from the second support structure to form a gap between the second end of the first support member and the second support structure.

[0026] In some embodiments, the vehicle further comprises a wheel assembly having a plurality of wheel assemblies spaced apart along the first direction, the wheel assembly being disposed at the second end of the first support member, or the wheel assembly being disposed at the lower portion of the second support structure.

[0027] In some embodiments, the carrier also includes a second locking structure, which is coupled to the associated structure and at least one of the first support structure. When the carrier is in the expanded state, the second locking structure locks the two adjacent first support members so that the two adjacent first support members cannot rotate.

[0028] In some embodiments, an angle θ is formed between the first support structure and the second support structure. When the carrier moves from the unfolded state to the folded state, the angle θ decreases.

[0029] Furthermore, the angle θ satisfies 0︒≤θ<180︒.

[0030] Furthermore, the carrier also includes a third locking structure, which is arranged between the first support structure and the second support structure. When the carrier is in the expanded state, the third locking structure locks the angle θ so that the first support structure and the second support structure cannot rotate relative to each other.

[0031] In some embodiments, the vehicle further includes a grip portion, which is rotatably connected to the second support structure. When the vehicle moves from an unfolded state to a folded state, the grip portion can be flipped clockwise or counterclockwise relative to the second support structure; a side panel is provided at the opening, which can be opened or closed and does not affect the folding of the vehicle. When the passenger enters the vehicle, the side panel can be opened to expose the opening; after the passenger enters the vehicle, the side panel can be closed to seal the opening.

[0032] Another technical solution adopted by the present invention is: a carrier, the carrier comprising:

[0033] A first support structure comprising at least two first support members, each of the first support members having a first end and a second end;

[0034] an associated structure, the associated structure being connected to the first end portion, so that the first support members can rotate relative to each other;

[0035] a second support structure rotatably connected to the second end portion;

[0036] a connecting structure, which is rotatably connected to the second supporting structure and the first supporting structure respectively;

[0037] The associated structure can be located in a first position or a second position. When the associated structure is located in the first position, each of the first support members is expanded along the first direction, the second support structure is away from the axis of the associated structure, and the connecting structure and the first support structure form an opening; when the associated structure is located in the second position, the first ends of each of the first support members approach and retract with each other, and the second support structure moves closer to the axis of the associated structure.

[0038] In some embodiments, the connecting structure includes two connecting members, the second supporting structure includes two second supporting members, and the first supporting structure includes two first supporting members. Each of the connecting members, each of the first supporting members, and each of the second supporting members are respectively arranged on both sides of the associated structure, and the connecting member and the second supporting member on each side form a seating area with the first supporting member respectively to form two seating areas arranged opposite to each other.

[0039] In some embodiments, the vehicle also includes a third support structure, and the third support structure and the connecting structure are respectively arranged on the upper and lower sides of the first support structure, and the third support structure has a first extension member and a second extension member, and the first extension member and the second extension member respectively extend from the first support structure in a direction away from the first support structure, and are connected to each other at the extension ends to form a stepping area on the lower side of the first support structure.

[0040] Due to the application of the above-mentioned technical solution, the present invention has the following advantages compared with the prior art: the carrier provided by the present invention has an opening formed between the connecting structure and the first supporting structure, so that the carried person can enter the carrier through the opening and can also get off the carrier very conveniently without the need for assistance from others, thereby reducing the burden on the caregiver.

[0065] The technical solution of the present invention is described in detail below with reference to the accompanying drawings and specific embodiments, so that the advantages and features of the present invention can be more easily understood by those skilled in the art.

[0066] Referring to FIG. 1 to FIG. 11 , a carrier is shown, which has a folded state and an unfolded state. The carrier includes:

[0067] A first supporting structure comprising at least two first supporting members 1;

[0068] an association structure 3, the association structure 3 being connected to the at least two first support members 1, respectively, so that each first support member 1 can rotate relative to the association structure 3;

[0069] a second supporting structure, which is rotatably connected to at least two first supporting members 1;

[0070] a connecting structure, the connecting structure being rotatably connected to the first supporting structure and the second supporting structure respectively;

[0071] When the vehicle is in the expanded state, the first supporting structure extends along a first direction, the second supporting structure extends along a second direction different from the first direction, and an opening H (such as the opening formed by the dotted line in Figure 5) is formed between the connecting structure and the first supporting structure, so that the carried person can enter the vehicle or get off the vehicle through the opening H; when the vehicle is in the folded state, the first supporting members 1 and the second supporting structures are folded together along the first direction.

[0072] Referring to Figures 1 to 11, in this embodiment, the second support structure includes two second support members 2, and the connecting structure includes two connecting members. Each connecting member and the second support member 2 are respectively arranged on both sides of the associated structure 3, and the connecting members on each side, the second support member 2, and the first support member 1 respectively form a seating area, so as to form two oppositely arranged seating areas. The two seating areas are arranged oppositely to facilitate communication between the carried persons. Although the vehicles disclosed in patent documents such as US4834415A, US20230057769A1, DE102021208364A1, CN104802884A, and CN202911778U have two seats, they do not have an opening H, which makes it inconvenient for the carried persons to get on and off the vehicle.

[0073] In this embodiment, each connector includes a first connector portion 4 and a second connector portion 5 that are rotatably connected to each other. The first connector portion 4 is also rotatably connected to the second support structure, and the second connector portion 5 is also rotatably connected to the first support structure. The position where the first connector portion 4 and the second connector portion 5 are rotatably connected can be closer to the upper portion of the seating area than to the lower portion of the seating area, thereby facilitating rapid folding of the carrier.

[0074] When the carrier is deployed, as shown in Figures 1 and 5 , the connecting structure, the first support structure, and the second support structure define a first surface of the carrier, which is also the outer surface of the carrier. An opening H is located on this first surface, and this opening H is located between the two seating areas. A person being carried can enter the carrier through the opening H and conveniently reach the seating area or disembark from the carrier through the opening H.

[0075] As shown in the accompanying drawings, the vehicle of this embodiment also includes a third support structure. This third support structure and the aforementioned connecting structure are respectively disposed above and below the first support structure. The third support structure includes a first extension member 6 and a second extension member 7. These first extension members 6 and second extension members 7 extend away from the first support structure and are interconnected at their respective extension ends, forming a stepping area B below the first support structure. A first space A is formed between the two seating areas and is connected to the opening H and the stepping area B, respectively. The provision of the first extension member 6 and second extension member 7 further stabilizes the quadrilateral formed by the first support member 1, the second support member 2, the first connecting portion 4, and the second connecting portion 5, thereby enhancing the structural stability of the vehicle when deployed.

[0076] In this embodiment, the first extension member 6 and the second extension member 7 are respectively rotatably connected to the first support structure, and the ends of the first extension member 6 and the second extension member 7 are rotatably connected to each other around a first pivot center line X1. The first pivot center line X1 is perpendicular to the first direction. During the conversion of the carrier between the expanded state and the folded state, the first extension member 6 and the second extension member 7 rotate relative to each other and are folded relative to the first support structure.

[0077] The line connecting the two projection points of the first pivot center line X1 and the axis line X0 of the associated structure 3 in the same vertical plane is perpendicular to the above-mentioned first direction. When the carrier moves from the unfolded state to the folded state, the first extension member 6 is folded with one first support member 1, and the second extension member 7 is folded with the other second support member 1.

[0078] As shown in Figures 1 and 5 , the connecting structure and first extension member 6 are pivotally connected to the first support structure about a second pivot axis X2. The connecting structure and second extension member 7 are pivotally connected to the first support structure about a third pivot axis X3. When the carrier is deployed, the axis X0 of the connecting structure 3 is positioned lower than the second and third pivot axes X2 and X3, facilitating the tight folding of the various rods when the carrier is collapsed.

[0079] In this embodiment, the first extension member 6 and the second extension member 7 are respectively integrally provided with at least a portion of the connection structure. Here, the first extension member 6 is integrally provided with the second connection portion 5 of one connection member, and the second extension member 7 is integrally provided with the second connection portion 5 of the other connection member.

[0080] In other embodiments, the first extension member 6 and the second extension member 7 are independent of the connecting structure, and the carrier further includes a first locking structure that couples with the connecting structure and the first extension member 6 or the second extension member 7, respectively, so that the connecting structure and the first extension member 6 or the second extension member 7 can be locked to each other. In other embodiments, the first extension member 6 and the second extension member 7 can be detachably connected to the first support structure, thereby forming a stepping area B below the first support structure. Here, the first locking structure can adopt a common and universal locking structure. Its specific structure is not the focus of the present invention and is not described in detail here.

[0081] 1 to 11 , each first support member 1 has a first end 1a and a second end 1b. The first end 1a is connected to the associated structure 3, and the second end 1b is connected to the second support structure. When the vehicle moves from the unfolded state to the folded state, the first ends 1a of the two adjacent first support members 1 rotate relative to each other, and drive the second ends 1b to move in conjunction so that the second ends 1b of the two adjacent first support members 1 approach each other.

[0082] A pivot structure is provided between the first support structure and the second support structure. The pivot structure is rotationally connected to one of the first and second support structures. When the carrier moves from the deployed state to the collapsed state, the second end 1b of the first support member 1 moves away from the second support structure, thereby forming a gap between the second end 1b of the first support member 1 and the second support structure. In one embodiment, as shown in Figures 1 and 2, the pivot structure includes a pin (not shown), a connector 24 fixed to the second support member 2, a pin hole 24a provided in the connector 24, and a pin hole 11a provided in the second end 1b. The pin passes through the aforementioned pin hole 24a and pin hole 11a to pivotally connect the connector 24 to the second end 1b. This pivot structure can effectively prevent the second end 1b and the second support 2 from interfering with each other when the first support member 1 rotates relative to the second support member 2.

[0083] The carrier also includes a wheel assembly 9, which has multiple groups of wheel assemblies 9 arranged at intervals along the first direction. The wheel assembly 9 is arranged at the second end 1b of the first support member 1, or as in the present embodiment, is arranged at the lower part of the second support structure. Specifically, several groups of wheel assemblies 9 are provided at the lower part of the two second support members 2.

[0084] The carrier also includes a second locking structure, which is coupled to the associated structure and at least one of the first support structure, so that when the carrier is in the unfolded state, the second locking structure locks two adjacent first support members 1, so that the two adjacent first support members 1 cannot rotate.

[0085] An angle θ is formed between the first support structure and the second support structure, and the angle θ satisfies 0︒≤θ<180︒. When the carrier moves from the expanded state to the folded state, the angle θ decreases from large to small. The carrier also includes a third locking structure, which is arranged between the first support structure and the second support structure. When the carrier is in the expanded state, the third locking structure locks the angle θ, so that the first support structure and the second support structure cannot rotate relative to each other.

[0086] The carrier also includes a grip portion 8, which is rotatably connected to the second support structure. When the carrier enters the folded state from the unfolded state, the grip portion 8 can be flipped clockwise or counterclockwise relative to the second support structure, thereby being folded relative to the second support structure.

[0087] The following uses the vehicle of the embodiment shown in Figures 1 to 11 as an example. When the vehicle is in the unfolded state and a user grips the grip portion 8 to push or pull the vehicle to drive it, the front, rear, left, right, and up, down directions are defined with reference to the directions viewed by the user to further explain the detailed structure of each part of the vehicle in this embodiment.

[0088] Referring to Figures 1 and 5, when the vehicle is in the unfolded state, the extension direction of the first support structure is along the front-to-back direction, that is, the aforementioned front-to-back direction is the first direction; the first support structure includes two first support members 1, each of which includes two first support rods 11 extending along the front-to-back direction and spaced apart along the left-to-right direction, and the two first support rods 11 located on the same side in the left-to-right direction are connected by an associated structure 3, and the associated structure 3 is internally coupled with a second locking structure.

[0089] 3 and 4 , the association structure 3 includes a first connection seat 31 and a second connection seat 32. The first connection seat 31 is fixed to one end of a first support rod 11; the second connection seat 32 is fixed to one end of another first support rod 11. The first connection seat 31 and the second connection seat 32 are rotatably connected around a rotation center line extending in the left and right directions. The above-mentioned rotation center line between the two constitutes the axis X0 of the association structure 3.

[0090] The second locking structure within the connecting structure 3 includes a locking member 33, an elastic member 34, and an unlocking member 35. The locking member 33 is a tooth-shaped member with multiple locking teeth on its outer periphery. Both the first connecting seat 31 and the second connecting seat 32 are provided with tooth-groove structures. The locking member 33 is disposed in the cavity formed between the first and second connecting seats 31, 32, and is axially slidable therein. The elastic member 34 is disposed between the second connecting seat 32 and the locking member 33 and is used to provide the force required for the locking member 33 to move toward the first connecting seat 31. The elastic member 34 is specifically a spring. The unlocking member 35 is axially slidable on the first connecting seat 31. When the locking teeth on the locking member 33 engage with the tooth-groove structures on both the first and second connecting seats 31, the connecting structure 3 locks the two first support rods 11, preventing relative rotation. When the unlocking member 35 is driven to slide, disengaging the locking member 33 from the tooth-groove structures on the first connecting seat 31, the two first support rods 11 can rotate relative to each other.

[0091] Referring to Figures 1 and 5 , when the vehicle of this embodiment is in its deployed state, the second support structure includes two second support members 2. The first support structure is positioned between the two second support members 2 along the front-to-back direction. The second support member 2 extends vertically and includes two second support rods 21 extending vertically and spaced apart in the left-to-right direction. Optionally, the second support member 2 also includes an upper crossbar 22 fixedly disposed between the upper portions of the two second support rods 21, and a lower crossbar 23 disposed between the two second support rods 21 and below the upper crossbar 22. The upper crossbar 22 can be integrally formed with the two second support rods 21 to form a U-shaped rod with a downward opening. The lower portion of each second support rod 21 is provided with a connector 24, extending perpendicularly to the longitudinal direction of the second support rod 21 and pivotally connected to the first support rod 11 on the same side of the first support member 1 via the connector 24. The lower portion of each second support rod 21 is provided with a set of wheel assemblies 9.

[0092] In this embodiment, in any connecting member of the connecting structure, the first connecting portion 4 includes two first connecting rods 41 spaced apart in the left-right direction, the second connecting portion 5 includes two second connecting rods 51 spaced apart in the left-right direction, and a second crossbar 52 fixedly mounted between the two second connecting rods 51. The first extending member 6 includes two first extending rods 61 spaced apart in the left-right direction, and the second extending member 7 includes two second extending rods 71 ​​spaced apart in the left-right direction. On each side of the vehicle, the first extending rod 61 is integrally provided with the second connecting rod 51 on the same side of one second connecting portion 5, and the second extending rod 71 is integrally provided with the second connecting rod 51 on the same side of the other second connecting portion 5; the extended ends of the first extending rod 61 and the second extending rod 71 on the same side are rotatably connected about a first pivot axis X1. An internal angle β is formed between the second connecting rod 51 and the first supporting member 1 adjacent thereto in the opening H. The angle of the internal angle β is not limited to the angle shown in FIG5 , and its angle value may be greater than 90° or less than 90°. The shape of the opening H is also not limited to the trapezoid shown in FIG5 , and may also be formed into other shapes according to the size of the internal angle β.

[0093] As shown in the accompanying drawings, in this embodiment, when the vehicle is in the deployed state, the first connecting portion 4 and the second connecting portion 5, as well as the first extension member 6 and the second extension member 7 on both sides are located between the two first support rods 11 and between the two second support rods 21 in the left-right direction. The second connecting portion 5 of one connecting member is rotatably connected to the first extension member 6 at the location where it meets the second connecting portion 5, which extends colinearly with the axis of the second crossbar 52. The second connecting portion 5 of the other connecting member is rotatably connected to the second extension member 7 at the location where it meets the second crossbar 52, which also extends colinearly with the axis of the second crossbar 52 in the second connecting portion 5 on that side.

[0094] On each side of the vehicle, one end of the first support rod 11 is rotatably connected to the second support rod 21 about a fourth pivot axis X4. One end of the first connecting rod 41 is rotatably connected to the second support rod 21 on the same side about a fifth pivot axis X5. The other end of the first connecting rod 41 is rotatably connected to one end of the second connecting rod 51 on the same side about a sixth pivot axis X6. The fourth, fifth, and sixth pivot axes X4, X5, and X6 are all parallel to the first, second, and third pivot axes X1, X2, and X3, as well as the axis X0 of the associated structure 3. The sixth pivot axis X6 can be located to the left or right of the second pivot axis X2, or on the same vertical line as the second pivot axis X2.

[0095] The first connecting rod 41 of the first connecting portion 4 has a first rod segment 41a and a second rod segment 41b connected along the length direction. When the vehicle is in the deployed state, the first rod segment 41a is parallel to the first direction, and the second rod segment 41b is inclined in the vertical direction and extends along the same length direction as the second connecting rod 51 on the same side; at least a portion of the first extension rod 61 and the second extension rod 71 is curved.

[0096] The grip portion 8 includes two push rods 81 spaced apart in the left-right direction, and a grip rod 82 fixed between one end of the two push rods 81. The two push rods 81 and the grip rod 82 are integrally formed into a U-shaped rod. The other ends of the two push rods 81 are rotatably connected to the upper end of the second support rod 21 on the same side. A fourth locking structure (not shown) is also provided at the rotational connection between the push rods 81 and the second support rod 21 to lock the grip portion 8 to the second support member 2.

[0097] The carrier of this embodiment is in its deployed state, as shown in Figures 1 and 5 . The connecting structure 3 is in its first position, the two second support members 2 of the second support structure are spaced away from the axis X0 of the connecting structure 3, and an opening H is formed between the connecting structure and the first support structure. Simultaneously, two seating areas are formed on either side of the connecting structure 3, formed by the first connecting portion 4, the second connecting portion 5, the first support member 1, and the second support member 2. The two seating areas face each other, and a first space A is formed between them. The opening H on the carrier communicates with this first space A. The first extension member 6 and the second extension member 7 cooperate to form a stepping area B below the first support structure. The first space A is located above the stepping area B and the two are connected to each other. A person being carried can enter the first space A through the opening H, sit on the seating area, and place their feet on the stepping area B.

[0098] FIG12 shows a schematic diagram of the vehicle shown in FIG5 after adding side panels 100. Zippers 101 are provided on the side panels 100, which can be opened from opening H, allowing the carried person to enter the seating area of ​​the vehicle from this position. In other embodiments, zippers 101 can be replaced with burrs, connectors, or other connecting structures. The side panels 100 can be made of flexible or elastic materials so that their presence does not affect the folding of the vehicle. When folding the vehicle, the side panels 100 can be removed in whole or in part, or the zippers 101 can be opened. Alternatively, the opening H can be omitted, or a detachable or openable door can be provided. The detachable door can be made of a rigid or flexible material, while the openable door can be made of a soft material and closed or opened using the zipper 101, burrs, connectors, or other connecting structures. The door can be provided as one or two doors, and the zipper 101, burrs, connecting buckles or other connecting structures can be provided on the side or in the middle of the door.

[0099] When the carrier needs to be folded, as shown in Figures 6 to 9, the second locking structure within the connecting structure 3 is unlocked, driving the connecting structure 3 to move upward. The two first support members 1 rotate relative to the connecting structure 3 and gradually retract in the front-to-back direction. On both sides of the connecting structure 3, the first connecting portion 4, the second connecting portion 5, the first support member 1, and the second support member 2 rotate relative to each other and gradually retract together in the first direction. The first extension member 6 and the second extension member 7 rotate relative to each other and retract in the first direction. The grip portion 8 is then rotated relative to the second support member 2, so that it is retracted to one side of the second support member 2.

[0100] As shown in Figures 10 and 11, the carrier is in a folded state, the associated structure 3 is in a second position, which is higher than the first position. The first end portions 1a of the first support members 1 of the first support structure are close to each other and folded together, the second support structure is close to the axis X0 of the associated structure 3, and the connecting member is folded along the first direction between the first support member 1 and the second support member 2. The carrier as a whole is in a very compact and flat state.

[0101] In summary, the vehicle provided in this embodiment has few structural components and a simple overall structure. When unfolded, it provides two seating areas. A person being carried can easily enter the vehicle through opening H and reach the seating areas. Within the seating areas, the person being carried can place their feet on stepping area B, making sitting more comfortable. Furthermore, the person being carried can easily disembark from the vehicle through opening H. This vehicle is suitable for carrying the elderly, adults, and children. The elderly and children, in particular, do not require assistance when getting on and off the vehicle, reducing the burden on caregivers. Furthermore, due to the design of the opening, the vehicle can be folded quickly and easily. Furthermore, the vehicle's overall structure is relatively simple, resulting in lower production costs.

[0102] In some other embodiments, in the first support structure, the number of first support members 1 can also be set to more than two, such as three or more, and the two adjacent first support members 1 are connected by an associated structure 3. When the vehicle enters the folded state from the unfolded state, the two adjacent first support members 1 rotate about the associated structure 3 and fold along the first direction. The rotation mode between the two adjacent first support members 1 can be clockwise or counterclockwise.
